'HELP! The game freezes when I talk to a shopkeeper!' This project's information has been moved to my WordPress. Competitive hold items are much more available, a 6IV Ditto is available through an in-game trade (holding a Destiny Knot), Eggs hatch in one cycle, and Level 100 Memento Blissey battles are available in the Battle Buffet once the main story has been beaten. In all Builds, some features are designed to make preparing competitive teams much less of a hassle. In Nova Sun and Umbra Moon's Legit Build, everything obtainable is 100% legal and legitimate for real online battles or trades. Melee's ' 20XX Hack Pack' which enables features for competitive players to practice and grind. Nova Sun and Umbra Moon's secondary focus is inspired by Super Smash Bros. The end-game of the main story features trainers with Levels in the mid-nineties. Every Pokémon in Trainers' teams has a hold item and a proper moveset. Every trainer in the game has been edited, and the level curve expects use of the Experience Share, which means that the player levels up very quickly. The premier feature of Nova Sun and Umbra Moon is the ground-up redesign of Pokémon Trainers in the world to increase the game's challenge. Like my Rutile Ruby and Star Sapphire hacks, their main purpose is to provide a more challenging game experience while not artificially limiting the player. Pokémon Nova Sun and Umbra Moon are mods for Pokémon Sun and Moon.
